The Shoulder Slide, with its closed chain shoulder stabilizing track system, can accommodate 40, 60 and 75-degree angles as well as vertical angles of shoulder elevation. This closed chain tracking system, assures a safe rehab that accelerates the recovery of many shoulder conditions.The Shoulder Slide contains an electro-biofeedback mechanism that enables the therapist to set a desired elevation for the patient. The electro-biofeedback is an audible signal which is heard when the patient reaches the elevation set by the therapist. As the patient improves, the set point is raised for goal oriented report ability. Increased resistance can be accomplished by simply adding on the weights provided. The importance of this unit lies heavily in its unique design in the overall rebuilding of the rotator cuff muscles within the shoulder.
